Memory chip giant Samsung Electronics has invested in a Chinese artificial intelligence technology developer as part of its efforts to catch up in the intensifying global race for AI platforms and devices, according to sources Sunday.

In August, Samsung made a significant investment in DeePhi Tech, a Tsinghua-based startup with deep learning technologies, a source told The Korea Herald.

“Samsung made quite a large investment in DeePhi Tech, which a group of Korean developers who met the startup’s officials found surprising,” the source said.

“Samsung appears to have made considerable investment in the Chinese company, in line with the Chinese government’s move to foster homegrown AI tech firms. The investment could have been made out of political consideration, not necessarily over the company’s technological prowess.”

It is the second investment Samsung has made in foreign AI tech startups following a $30 million investment in the UK-based Graphcore last October.

Samsung is listed as one of the partner businesses on DeePhi Tech’s homepage, along with China’s fabless chipmaker Mediatek, US fabless Xilinx and cloud service provider Amazon Web Services.

DeePhi Tech is a deep learning solution developer that was founded in 2016 by four co-founders who graduated from Tsinghua University and Stanford University.

The company draw attention from tech giants like Samsung due to its neural network compression technology and neural network hardware architecture.

SK Telecom, a Korean mobile carrier that is also passionate about its emerging AI business, had also offered an investment to the Chinese startup this summer, but the company turned down the offer, the source said.

DeePhi Tech offers the Deep Neural Network Development Kit, known as DNNDK, which is a deep learning software development kit designed as an integrated framework that aims to simplify and accelerate deep learning applications.

Such AI chipsets, known as neural processing units, or NPUs, are at the height of market attention as a means to widen the use of AI programs, especially in smartphones.

At a seminar held at the Semiconductor Exhibition 2017 on Thursday, Kim Il-san, a senior researcher at Samsung Electronics’ system LSI business, said the adoption of NPUs in smartphones will be mainstream in the near future.

“Because it is inefficient to have the current CPUs in smartphones to process deep learning algorithms, adding NPUs will become a mainstream trend,” Kim said. “It is still difficult to comment on NPU adoption in the following Samsung Galaxy phones.”

Samsung’s semiconductor business appears to be ramping up its R&D efforts on AI chipsets lately, after an announcement by Huawei’s AI chip Kirin 970-equipped Mate 10 smartphone series.

On Thursday, Samsung Advanced Institute of Technology, a control tower for future technologies, held a two-day seminar on development of AI technologies by inviting globally renowned scholars as part of the ongoing move.

“Many Samsung units are accelerating research on the development of AI at their own level,” said Yoo Hoi-joon, a professor at the Korea Advanced Institute of Technology.

Samsung and DeePhi were not available immediate comments as of Sunday. A Samsung official said that the latest investment in the Chinese firm may be part of the company‘s direction towards increasing investments in AI-related startups around the world.
